Bio fuels are basically the alternative fuels for the petroleum based fuels. They are thought to be energy conserving, pollution free and environment friendly.

Actual Facts about the Bio-fuels

They are basically prepared from the biological materials and the purpose behind their usage is that they pollute the environment comparatively less than the petroleum based fuels. But the reality is somehow converse to it. It is found that the amount of carbon dioxide released by the Bio fuels in the environment is four times larger than that of petroleum based fuels. These findings are recently released by the European Commission in Brussels, released under the Freedom of Information Act. The particular ones are the oils used for fuel extracted from the soybean biomass.

Negative Aspects

Use of Biofuels

If we put the concentration of carbon contributed to the environment by the usage of Bio-fuels, there is another important factor that must be considered regarding its preparation. Most of the Bio-fuels are prepared by exacting the oils from the plant sources. This destroys the plant life and is likely to cause certain problems in the ecosystem.

After that, once they have been prepared, their burning produces too much of the carbon dioxide gas in the environment that is harmful both for the plant and animal life. The ratio of oxygen in such environment ultimately gets lowered.

The Basics of Biomass Fuel

Tags: , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,


Biomass fuel is organic substance used to produce heat by the process of combustion. Bio mass energy, bio fuel or biomass fuel are interrelated terms. The biomass is used to make different products like electricity, solid and gaseous fuels and chemicals. Given below are some of the facts relating to biomass energy.

Renewable Energy Source

Yes, biomass is a renewable energy source which means that the resource is not going to end for millions of years.

Biomass Energy

The rising prices of fossil fuels have intensified the need of using renewable energy sources. The crops and animal wastes are major sources of biomass fuel. Biomass is a byproduct obtained from sugar cane, manure etc. So as long as there are living things on earth the biomass is not going to end. In the U.S the biomass is the second major renewable energy source.

Sources for Biomass Energy

There can be many types of crops which can be grown in diverse conditions to obtain biomass fuel. This ensures large scale production of biomass fuel. However, competition with other food or cash crops can be an issue in countries which have less area available for growing crops. Biomass can also be obtained from natural forests. Ethanol is a notable biomass fuel. It can be produced by fermentation of any biomass rich in carbohydrates.

The process of generating electricity from steam comprises following parts: a firing subsystem (biomass combustion), a steam subsystem (boiler and steam delivery system), a steam turbine with electric generator, as well as a feed water and condensate system.Biomass-energy

Biomass-energy

1.  Renewable energy

Energy obtained from sources that are essentially produced at a rate higher than the rate of consumption. Renewable sources of energy include biomass, geothermal, wind, photovoltaic, and solar thermal energy.

2.  Biomass

Biomass is any plant and plant- derived material obtained from photosynthetic reaction of carbon dioxide with water vapor. Using biomass in the context of energy source, biomass can also include woody plants, residues from agriculture or forestry, and the organic component of municipal and industrial wastes. Biomass qualifies as a renewable source of energy as long as it is used at a rate comparable to or less than the rate of production Read the full story

Benefits of Bio-fuels

It’s a well known fact that fossil fuels have toyed with our environment and this has resulted in pollution and global warming besides many other issues. Now with the awareness of environmental hazards and the entire world going green, the popularity of Bio-fuels is growing by the day

Biological Fuels or Bio-fuels are prepared from reusable or recycled materials. And thanks to the modern-day scientific research, bio-fuels are playing a vital role in contributing to the world a number of benefits. Below are just some of the benefits illustrated. Read the full story

Before we begin a discussion on biomass technology, we should understand what exactly is biomass and why we should use it for energy sources.

What Is A Biomass

According to definition biomass means the organic material derived from plants and animals. It is a chemical composition of carbon, organic hydrogen molecules, atoms of oxygen, nitrogen and alkaline earth. Plants are the first absorbents of energy provided by the sun, and when animals eat plants, then it becomes animal biomass.

Conversion of Biomass into Energy

Ancient way of converting biomass into energy is just to burn it for producing heat, as humans practiced it for thousands of years. Still this is the most common way for conversion of biomass into energy in United States and elsewhere also.

Biomass conversion into Energy

The heat generated from biomass can be used for heating, cooking, and industrial processes, or for producing electricity.

Using biomass for burning haves some problems regarding some energy waste and also some air pollution if it is not carefully controlled.

United States already generate 45 billion kilowatt-hours of electricity from biomass and that is 1.2% of whole United States electric sales.

Potential for Biomass Energy

United States also produce 4 billion gallons of ethanol, which is almost 2 percent of the liquid fuel used in cars and trucks. Same like that contribution for heat is also considerable. But still it can be produced more by better conversion technology and more attention paid to energy crops.

There are many benefits of biomass energy but an appropriate use is required for reaping these benefits. The benefits of Biomass Energy are given below:

Small Carbon Footprint

As compared to fossil fuel the carbon footprint of biomass energy is small which is one of the major benefit of biomass energy. When new plant material is available to replace the used material, no net carbon dioxide increase is produces by biomass energy. Bio power reduces fossil fuel consumption which also reduces the release of carbon dioxide, this seems to be a good news but there is a problem that fossil fuels are often used for manipulation and harvesting of biomass.

Some Facts About Solar Energy

Our Earth receives 174 petawatts (PW) of solar radiations at the upper atmosphere, out of which almost 30% is reflected back to space whereas the rest is absorbed by clouds, oceans and land masses.solar energy

The Earth’s land surface, oceans and atmosphere that absorb solar radiation, raises their temperature. This causes warm air that contains evaporated water from the oceans to rise, causing atmospheric circulation or convection.

The water cycle gets completed when the air reaches a high altitude, where low temperature prevails, and the water vapor condenses into clouds, which rain onto the Earth’s surface.

Microbes Produce Fuel Directly From Biomass

According to a collaboration led by the Researchers from the U.S. Department of Energy’s Joint BioEnergy Institute (JBEI), they have successfully developed a microbe that can produce an advanced biofuel directly from biomass.

microbes for Biofuel

Making use of synthetic biology, the JBEI researchers have engineered a strain of Escherichia coli (E. coli) bacteria to produce biodiesel fuel and other important chemicals that are derived from fatty acids.

The Chief Executive Officer for JBEI, Jay Keasling said that the fact that microbes can produce a diesel fuel directly from biomass with no additional chemical modifications is exciting and important and a leading scientific authority on synthetic biology.

In the context of renewable energy, biomass means both recently deceased and living biological materials such as plant & animal matter, dead trees, yard & wood chippings, which help in the production of chemicals and heat as well as bio-fuel. Oh and lets not forget biodegradable wastes too that can be burnt as fuel too.
